Hunt looping

We have an extension 30000 with "Call Forward Busy" and "Call Forward No Answer" setup to a hunt pilot 80001. Within the linegroup, we have 3 DNs as below.

30001

30002

30003

We don't have voicemail yet. Thus at the end of hunting, we call forward back to 30000 and it will start the same hunting again as below.

30001

30002

30003 --> call forward back to 30000

Has anyone tried this? Once we have voicemail, we will setup call forward to the voicemail at the end of hunting as below.

30001

30002

30003 --> call forward to voicemail

Thanks.

Re: Hunt looping

I think that should work, except that it will be an endless loop. If no one picks the call, the caller will keep on hearing rings with out any answer, which can be frustrating.

Yep - the CFB/CFNAs won't effect the hunt group operation...

Absolutely - I've installed plenty of these no problems and everything I've done so far is UK based...

Re: Hunt looping

Thanks for the reply.

Yes, it will be endless loop. This is only a temp. solution before we have vm.

When the DNs in the line group, the DNs CFB and CFNA setting will be ignored. Is that the case?

Line group

==========

30001's CFB/CFNA setting will be ignored

30002's CFB/CFNA setting will be ignored

30003's CFB/CFNA setting will be ignored

Thanks again.

Re: Hunt looping

Hi Aaron,

Thanks for the help.

Our client will open a office in London UK very soon and will install a 3845 router with E1 module. Any idea if this voice module can be supported in UK?

1-port RJ-48 Multiflex Trunk E1 (VWIC-1MFT-E1)

Thanks again.

Re: Hunt looping

Thanks. Aaron

We are about to install 3845 with VWIC-1MFT-E1 in London UK, and it will be managed by CCMv4.1(3) which is located in Tokyo. (A single CCM centralized cluster envirnoment) As we have not much experience to setup E1 module, is it possible to post a workable 38XX E1 config?

Attached below is the post of current 3825 T1 config in Tokyo and the MGCP/Gateway config in CCMv4.1(3)

2b. Inbound Calls

2c. Outbound Calls

2d. Product-Specific Configuration

Believe we need to change some of the setting in CCM such as "Global ISDN Switch Type", "PRI Protocol Type", "PCM Type" etc to communicate this E1 module in London. Could you shed us some light on this?

Thank you so much in advance.

Re: Hunt looping

That module should work. Make sure you work with your Telco as far as signalling parameters, switch type etc.

Re: Hunt looping

Additionally, I would suggest getting vwic2-mft-t1/e1. Its the same price as the generation 1 vwics which are either t1 or e1 and not both. This card also has capability to home upto two echo cancellation modules (on hardware).

Also make sure you have the right amount of DSPs to support an E1.You may use the PVDM slots on the mobo of the router.

Here is a link to DSP calculator.
